In this chapter, the accelerator-driven systems (ADS) are described. Since ADS are closely related to MSR, several topics are described: an introduction, a typical application of an Accelerator Molten Salt Breeder (AMSB) for fissile production, an application of minor actinide incineration, and a low-energy linear ADS application.

The second one is more important, because it could provide global solution for the energy problem, especially for Third World countries. As mentioned above, proton accelerator is crucial element of the ADS.

Experimental Modeling of Accelerator - Blanket System

Accelerator-driven systems (ADS)– sub-critical systems with external sources have been widely discussed in recent years. The ADS objective could be to treat the spent fuel or WG Pu, destroy the trans-uranics and selected fission products, and prepare the resulting reduced waste for permanent disposition in a geologic repository.

Study of an External Neutron Source for an Accelerator

This study describes a conceptual design of an accelerator-driven subcritical (ADS) system for disposing of this SNF inventory by utilizing the 131 tons of MAs inventory and a fraction of the plutonium inventory for energy production, and transmuting some long-lived fission products.

thorium: cleaner nuclear power?

Thorium: Cleaner Nuclear Power?

The accelerator driven system (ADS) can use thorium as the primary fuel. To get the thorium cycle going it uses a particle accelerator to fire protons at a lead target. The lead then releases neutrons that hit nuclei in the thorium fuel, starting the fuel cycle. In the ADS, the protons cause the fertile (not fissile) fuel to fission.

Recently, the accelerator-driven systems (ADSs), which are used for production of neutrons in spallation neutron source and can act as an intense neutron source in accelerator-driven subcritical reactors, and their neutronics have been studied by many researchers [15–20]. Most of the studies were concerned with specific design concepts and the production of neutrons from spallation reactions.

Preliminary analysis of radiation characteristic at upper

The ADS model used in the paper was composed by a subcritical reactor, a LBE spallation target, and a 250 MeV proton accelerator with maximum current of 10 mA. The subcritical reactor consisted of reactor vessels including components inside the vessels, side biological shielding, cover, rotating plugs and containing compartment.
